摘　　要：目的了解2014年-2016年丽水市食源性病原体的流行病学特征,为制定防治策略提供依据。方法收集2014年-2016年丽水市883例腹泻患者粪便标本,均进行诺如病毒、轮状病毒和致病菌的检测,分析检测结果。结果 883例腹泻患者标本,353例病原体阳性,总阳性率为39.98%。其中诺如病毒阳性率为21.52%,以Ⅱ型病毒感染为主,轮状病毒阳性率为16.99%,致病菌阳性率为5.32%。34例患者发生不同类型病原体的双重感染,无三重感染检出。0岁~3岁病原体阳性率最高,随年龄增长呈下降趋势。不同年份致病菌阳性率无显著差异,但诺如病毒和轮状病毒易暴发流行。病毒感染主要发生于秋冬季,致病菌感染主要发生于夏秋季。致病菌以沙门菌感染为主,易发生耐药。结论秋冬季节易发生病毒感染,夏秋季节易发生致病菌感染,可根据不同季节病原体的流行特点做好预防工作。Objective To understand the epidemiologic features of food -borne pathogens in Lishui during 2014 -2016, so as to provide scientific strategic basis for establishing treatment and prevention measures. Methods A total of 883 excrement samples from diarrhea patients in Lishui were collected during 2014 2016 for the detection of norovirus, rotavirus and food borne pathogenic bacteria. Then the results were analyzed. Results In the 883 samples from diarrhea patients, pathogenic detection was positive in 353 samples, with the total infection rate of 39.98%. The positive rate of norovirus was 21.52%, with type II virus infection as the major cause. The positive rate of rotavirus was 16.99% and the positive rate of pathogenic bacteria was 5.32%. Thirty four patients had dual infections with different types of pathogens and no triple infection was detected. The positive rate of pathogens in patients at 0 3 years old was the highest, and decreased with age. There was no significant difference in the positive rate of pathogenic bacteria in different years, but norovirus and rotavirus were prevalent. Viral infection mainly occurs in autumn and winter, and pathogenic bacteria infection mainly occurs in summer and autumn. The pathogenic bacteria are mainly Salmonella infection and susceptible to drug resistance. Conclusion Viruses are prone to occur in autumn and winter, and pathogenic bacteria are prone to occur in summer and autumn. Preventive work can be done according to the epidemic characteristics of pathogens in different seasons.
